Question

What is diffusion of substances? Explain in brief. Also give 2 examples.​

Answer 1

Answer:

Diffusion is the process of movement of molecules under a concentration gradient.The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout. Liquid and gases undergo diffusion as the molecules are able to move randomly.

Example:-

●Balloons. Ever notice how helium balloons slowly lose their lift.

●Food Coloring. A drop of food coloring in a glass of watercolors the water through diffusion.

→ EXAMPLES OF DIFFUSION :

→ A spray of perfume or room freshener will get diffused into the air by which we can sense the odour.

→ By adding boiling water into the dried noodles, the water diffuses causing rehydration and making dried noodles plumper and saturated
